Answer:

The last answer or Distance a number is from zero

Step-by-step explanation:

It's this answer because absolute value is just how far a number is from zero for example | -1 | is equal to 1 because -1 is 1 away from zero. Hope this helps :)

Answer:

The last answer or Distance a number is from zero i think i dont know

Step-by-step explanation:

Answer: 12

Step-by-step explanation:

Find the difference between the first and second points.

Since the x-coordinates are the ones changing, find the difference between them.

2 - (-3)

= 5

Then find the distance between the second and the third points.

Here, the y coordinates are the only ones changing, so we subtract them/or find the distance between them.

2-(-5)

=7

Now add the distances (5+7) and you get 12.

hope this helps!!:)

Answer:

Two ways to solve is to just do column addition or split 200+50+7 and add it to 400+30+8 first add 200+400 = 600, 50+30=80, 7+8 = 15. Add 600+80+15= 695.

Answer:

I think the answer is 21

Step-by-step explanation:

The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.

Answer:

21

Step-by-step explanation:

14 : w = 26 : 39

w = 14 * 39 : 26

w = 21

Answer:

2^-1

Step-by-step explanation:

2^2 *2 / 2^4

We know that 2^2 * 2 = 2^2 *2^1

a^b*a*c = a^(b+c)  so 2^2*2*1 = 2^(2+1)+ 2^3

2^3 / 2^4

We know that a^b / a^c = a^(b-c)

2^3 /2^4 = 2^(3-4) =2^-1

The equivalent of the given expression 2² × (2/2⁴) when simplified is; 2⁻¹

We are given the exponents expression;

2² × (2/2⁴)

Let us first multiply out the numerator to get;

2² × 2 = 2³

Thus, our overall expression is;

2³/2⁴

According to laws of exponents;

a^(b)/a^(c) = a^(b-c)

Thus;

2³/2⁴ = 2³⁻⁴

⇒ 2⁻¹

Answer:

186 cm²

Step-by-step explanation:

*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.

*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.

Left rectangle:

A = lh

A = 12 (8)

A = 96 cm²

Right rectangle:

A = lh

A = 10 (9)

A = 90 cm²

Total:

A = 90 + 96

A = 186 cm²

Answer:

Divide the number of contestants by 4 and when there is 120 contestants there is 30 winners

Step-by-step explanation:

Looking back at past sequences we can see that when we had 8 contestants we had 2 winners 8/4=2 and we also saw 16/4=4 so that was the formula now we just had to do it on 120 contestants and now we get 30 winners....Hope this helps! :)

Answer:

Step-by-step explanation:

The ratio of contestants to winners is 4 : 1 so to find the number of winners you must divide by 4, so you must divide 120 by 4, which is 30.

Answer:

  Each term in the pattern will be odd.

Step-by-step explanation:

The first differences are ...

  7 -3 = 4

  15 -7 = 8

These differ by 4, and the second is double the first.

These relationships between the first differences give rise to two possible sequences: a) an exponential sequence; b) a quadratic sequence. We can use a graphing calculator to find the coefficients of each of the patterns.

Exponential Sequence

  a[n] = 2·2^n -1

  The sequence is 3, 7, 15, 31, 63, 127, 255, 511, 1023, 2047.

  The 10th term is 2047.

Quadratic Sequence

  a[n] = 2n^2 -2n +3

  The sequence is 3, 7, 15, 27, 43, 63, 87, 115, 147, 183.

  The 10th term is 183.

__

Based on the above, the only thing we can say about these sequences is that they are all odd numbers.

Clearly, the 10th term is not 30. 7 is not a multiple of 3, so that observation fails immediately. 15 is not prime, so that observation also fails immediately.

_____

Additional comment

The differences of first differences are called "second differences". The differences of those are "third differences". and so on. If you keep taking differences of a sequence described by a polynomial, the n-th differences being constant means the sequence is described by an n-th degree polynomial.

Here, if we assume the 2nd differences are constant at 4, then the sequence is described by a 2nd-degree polynomial. (Similarly, constant first-differences are described by a 1st-degree polynomial--a linear function.)

If sequential levels of differences are all exponential sequences, then the sequence itself is an exponential sequence. As here, it may have a vertical offset. The base of the exponential will be the common ratio of the differences. (Here, the first differences have a ratio of 8/4 = 2, so the sequence could be exponential with a base of 2.)

Answer:

-25 feet

Step-by-step explanation:

We know that the change in altitude for the air balloon is -1500 feet, all within a span of 60 minutes, which then we are asked what is the rate of change.

To find the rate of change, we have to be able to divide a number by both sides that will not give us a decimal or very odd number. To avoid getting a decimal, divide both sides by 60.

-1500/60 = -25

60/60 = 1

So the rate of change would be -25 feet

Answer: 45 units

Step-by-step explanation:

Find the coordinates of R and S

R = -25

S = 20

Then just subtract them to find the distance between them.

20 - (-25) = 45.

Answer:

45

Step-by-step explanation:

First, find out the specific locations of R and S: for R, it is-25, and for S, it is 20 (use the tick marks on the x-axis).

Next, to find out the distance between R and S, be sure to add the absolute value, rather than the actual numbers.

So, ∣R∣ + ∣S∣ = 25 + 20 = 45

Answer:

20

Step-by-step explanation:

h(1) = -10

h(2) = -2

Let n=3

h(3) = h(3-2) * h(3-1)
